Tricuspid Valve

• A valve that opens from the left atrium to the left ventricle.

• A valve that is situated at the opening of the right atrium of the heart into the right ventricle and that resembles the mitral valve in structure but consists of three triangular membranous flaps.

• A valve that prevents backflow of blood into the right atrium.

• A valve located between the aorta and the left ventricle.

Artery

• A type of blood vessel that carries blood away from the heart.

• A type of blood vessel that carries blood towards the heart.

• A type of blood vessel that only transports oxygenated blood.

• A type of blood vessel that is involved in nutrient absorption.

Diastole

• The stage of the heart cycle in which the heart muscle is contracted, pumping blood out of the chambers.

• The stage of the heart cycle in which the heart muscle is relaxed, allowing the chambers to fill with blood.

• The phase of the heart cycle where the heart is at rest and not pumping blood.

• The period between heartbeats when the heart is preparing to contract again.

Pulmonary Circulation

• The process of blood flow from the left atrium to the left ventricle and into the aorta.

• The passage of venous blood from the right atrium through the right ventricle to the lungs for oxygenation and back to the left atrium.

• The movement of oxygenated blood from the lungs to the heart and then to the body.

• The circulation of blood solely within the heart chambers.

Atrium

• An anatomical cavity or passage; especially a chamber of the heart that receives blood from the veins and forces it into a ventricle or ventricles.

• A type of blood vessel that carries oxygenated blood away from the heart.

• A muscular wall that separates the left and right sides of the heart.

• A valve that regulates blood flow between the atrium and ventricle.

Superior Vena Cava

• A vein that returns blood to the right atrium of the heart from the lower half of the body.

• A vein that is the largest vein in the human body and returns blood from the brain.

• A vein that is the second largest vein in the human body and returns blood to the right atrium of the heart from the upper half of the body.

• A vein that carries oxygenated blood from the lungs to the heart.

Vein

• A vessel that returns blood to the heart.

• A type of artery that carries oxygenated blood.

• A structure that filters waste from the blood.

• A chamber of the heart that pumps blood.

Tissue

• An integrated group of cells with a common function, structure, or both.

• A single type of cell that performs a specific function.

• A collection of organs working together to perform a function.

• A type of fluid found in the body.

Cell

• The smallest structural unit of living matter capable of functioning independently.

• A group of tissues working together to perform a specific function.

• The basic unit of life that can only exist in multicellular organisms.

• A type of organelle found within a cell.

Aortic Valve

• A valve that separates the left atrium from the left ventricle.

• The semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle.

• A valve that controls blood flow from the right ventricle to the pulmonary artery.

• A valve that prevents blood from flowing back into the right atrium.
